る。2. Description of the Related Art According to the present invention, medium / high voltage (for example, 20 kV / 400 kV) can be achieved by a transmission line of several hundred meters.
Unlimited unique applications can be achieved in electrical energy generation sets with medium voltage (eg 20 kV) generators connected to substations. The current flowing through this transmission line is quite high (eg, about 20 kA), and a conductor with a large cross section (diameter: 500 mm) is usually used, but this conductor is a fluid (generally air) circulating in a metal conduit with a large diameter (usually 1 meter). ) Is cooled by. The loss in such a transmission line is about 3000 kW / km / GW.

では存在しない。Attention has been drawn to the realization of this transmission line using superconductors of low critical temperature, which enable low loss transmission at fairly high current densities. Such a transmission line requires many complicated low temperature facilities. This is because the helium (4.2 K) is kept at a low temperature so as to be liquefied. More expensive, but requires the use of large amounts of insulating material to acceptably limit low temperature losses. For this reason, such transmission lines do not currently exist.

る。Further work has been done on the use of superconductors to limit short circuit currents. By utilizing the characteristics of superconducting materials, it is possible to shift from a superconducting state in which there is almost no resistance beyond the critical value of current to a normal state in which the resistance is considerably high. If not limited, the value of the short-circuit current, which is at least 20 times the value of the rated current, can be limited to a predetermined value such as 5 times the value of the rated current. This limitation avoids any disturbance that might be caused by short circuit current. It can also provide significant benefits with regard to sizing of transmission lines, generators and transformers.
